# Deprecated Values

###### NTC 100K beta 3950
## Removal of `NTC 100K beta 3950` sensor type.

The "NTC 100K beta 3950" temperature sensor is _deprecated_ and will be removed in the near future. 

In order to solve the problem search in your config for `sensor_type: NTC 100K beta 3950` and replace it with `sensor_type: Generic 3950`.

Most users will find the "Generic 3950" temperature sensor more accurate. Anyway you can continue to use the older (typically less accurate) definition. Therefor define a custom thermistor with `temperature1: 25`, `resistance1: 100000`, and `beta: 3950`.
